Resumo: | The objective was to determine the effect of feeding system and time of the year on the in vivo and carcass characteristics of lambs slaughtered at the Cooperative Cooperaliança (Guarapuava-PR). Ile de France lambs and their crossbreds (n=253) were evaluated at slaughter with 39.6 kg of mean body weight in three periods between April and September 2010. Four feeding systems for finishing of lambs were identified: a) grazing dams + lambs with creep-feeding for lambs (n=67); b) no supplemented, grazing dams + lambs (n=47); c) grazing dams + lambs, all of them supplemented with concentrate (n=30); d) irregular system of feeding (n=109). Measurements on lambs were carried out in vivo and by ultrasound before slaughter and the carcass measurements were taken before and after chilling. Lambs delivered for slaughter between the end of August and the first half of September showed better results (p <0.05) for muscle development, dressing percentage and fat thickness in the carcass compared to that slaughtered in April and June. It was concluded that the feeding system with supplementation for dams and sucking lambs resulted in better characteristics for body and carcass measurements compared to other systems. |

Cordeiros Ile de France e cruzados (n=253) foram avaliados quando apresentavam, em média, 39,6 kg de peso corporal ao abate, e em três períodos, entre Abril e Setembro de 2010. Foram identificados 4 sistemas alimentares na terminação dos cordeiros: a) ovelhas em pastagem + cordeiros (creep-feeding; n=67) ; b) ovelhas + cordeiros em pastagem e não suplementados (n=47); c) ovelhas e cordeiros em pastagem e suplementados com ração concentrada (n=30); d) sistema irregular de terminação (n=109). Foram realizadas medidas in vivo e por ultrassonografia antes do abate e medidas na carcaça antes e após refrigeração. Cordeiros entregues para o abate entre o final do mês de agosto e a primeira quinzena do mês de setembro apresentaram resultados superiores (p<0,05) quanto ao desenvolvimento muscular, rendimento de carcaça fria e espessura de gordura subcutânea na carcaça, quando comparados aos abatidos nos meses de abril e junho. Concluiu-se que o sistema de alimentação com suplementação das ovelhas e cordeiros não desmamados resultou em melhores características para as medidas corporais e na carcaça, comparado aos demais sistemas.
